An electrical insulator is a material that does not easily conduct an
electric current. Materials typically used to insulate include
varnish is used. Insulating
gases such as
Sulfur hexafluoride are used in some
Wires that carry electric currents are usually insulated so the electricity goes to the right place.
Insulator can mean not only the
material but things that are made of that material. They are made of various materials such as:
silicone, rubber, plastic, oil, wood, dry cotton, quartz, ceramic, etc.
The type of insulator will depend on the uses. Insulators have high
electrical resistivity and low conductivity. The insulators prevent the loss of current and make the current more efficient by concentrating the flow.
